Forecast about the disaster of zoumaling tunnel discharge with fuzzy clustering analysis

Clustering analysis made more rapid progress in recent decades and is a new mathematical method used most widely. Its basic task is to classify examination objects. In the paper, to take a karst tunnel for an example, the author regards chemical composition of fountain and inundation in this tunnel as research objects and undertakes fuzzy clustering analysis, then explains analytic result combined with geologic conditions. So groundwater system of tunnel locality can be zoned exactly, reasons of tunnel inundation can be found, potential karst pipes can be proved up, the possibility of disasters of water burst can be forecasted.
